///I////4V//Illll/// Patented Dec. 9, 1930 UNITED STATES PATENT FFICE JOSEPH MONKHOUSE, OF GUELPH, ONTARIO, CANADA EXCELSIOR-CUTTING MACHINE Application filed May 27, 1929. Serial No. 366,424.

' length of the block without breaking the grain or threads, obviating the short grain waste of other machines.

I accomplish this by means of cutters and combs on horizontal plane members attached to an endless link belt which will travel at high speed along the whole length of the block which is forced up against said cutters by means of hydraulic or other elevating means.

I illustrate my invention by means of the accompanying drawings in which Figure I is a side elevation of my new or improved encelsior cutting machine.

Figure II is'a plan of same.

Figure III, is a sectional end view.

Figures IV and V are detailed views, while Figure VI is a perspective view of the inner'side of the cutting planes.

Similar letters of reference indicate simi lar partsin all the drawings.

A are the planing links connected by the pins (a) into an endless link belt, which revolves horizontally on the pulleys P carried in the usual bearings on the pillow blocks (p). The outer side of the links A are each provided with a row of studs forming a comb for grooving the log, followed by a planing knife also set in the outer side of the links A as shown in Figure IV. The inner sides of the links A. are concaved so as to fit the pulleys P over which they revolve. Longitudinal bars B are attached to the pillow blocks (39) and are provided with rollers (72) on their under sides. Figure V, which serve to eliminate the friction and hold the links A firmly against the upward pressure of the blocks controlled by hydraulic or other suitable elevating means.

As will be seen in Figure VI, the ends of the planing links are flattened so as to ride on the rollers (b) on the under sides of the bars B. C is a hydraulic ram for elevating the tray (0) in which are placed the wooden blocks to be operated upon. can be secured in position by screw clamps at either or both ends. The flat ends of the links A project beyond the sides of the pulleys P upon which they revolve and do not come into play until they are under the bars B. The carrying trays (0) slide on the table D carried by the hydraulic ram 0 and can i be withdrawn from either end of the machine when the block being operated upon has been planed away and a new tray with new blocks. slides into its place from either end. The vertical. pillers E are guides for the hydraulic press and carry stops (6) to control its motion. Either or both of the pulleys P can be operated by means of a driving pulley F, Figure II, mounted on the same shaft in the usual manner.

As will readily be seen, the planing links forming the link belt (revolving at high speed) plane off the top of the block or log beneath them which has beenraised by means of the hydraulic ram C, the cutting continues the full length of the machine which may be of any required length and cuts a straight strip from the log being operated upon.

The central inner concave sides of the links A can be provided with layers of wood or leather facing material so as to increase the friction thereof.

What I claim and desire by secure by Letters Patent is I In combination with an excelsior cutting machine composed of a plurality of cutting and scoring planes formed into an endless link belt, scoring and planing units with flat outer sides in which are inserted the scoring studs or pins, and planing knife, the central part of the inner side being concaved and faced with wooden or leather friction layers, the projecting ends of said scoring and planing units being flattened and adapted to pass over parallel, closely spaced friction rollers attached to the under sides of carrying bars;

and narrow smooth faced driving pulleys which fit the concaved rear sides of the scoring and planlng units.
